- Be careful when extending classes from structs. Their superclasses are essentially anonymous classes, so reopening them can be difficult. If you attempt to reopen them by extending them from “the same” struct, it will actually be a different anonymous class.
Ever had an STI model but wanted the views and controllers to pretend like it all extended the base class? You can have rails change the params namespace that it uses like so:buy ultram online
form_for :user, @admin_user, :url => user_path(@admin_user)
Or you can be super-cool and use polymorphic routes:valium online no prescription

becomes method is part of ActiveRecord, and it actually creates a 2nd copy of the object with the same attributes and a different class (shallow copy). Due to this implementation, it has limitations so use it carefully.
- Upgrading to rails 2.3.3 breaks HopToad. This is related to filter_parameter_logging, and it’s technically rails’ fault. It has been fixed in 2.3.3 stable (which I assume will be released as 2.3.4). You can also fix it yourself with a one-line-patch. Personally, I’d wait to upgrade till 2.3.4 comes out.
